product-capability
by affaan-mproduct-capability turns PRD intent, roadmap asks, or product discussions into an implementation-ready capability plan with constraints, invariants, interfaces, and unresolved decisions. Use it for Requirements Planning when multi-service work needs a durable product-capability skill artifact instead of vague planning prose.
This skill scores 79/100, which means it is a solid listing candidate for directory users who need a structured way to turn product intent into implementation-ready capability constraints. It is strong enough to install because it gives a clear trigger, a defined workflow target, and explicit rules against inventing product truth, though it would benefit from more operational examples and supporting artifacts.
- Clear triggerability: it explicitly targets PRDs, roadmap items, founder notes, and cross-service features where hidden constraints need to be surfaced before coding.
- Operationally useful artifact guidance: it points users toward a durable capability manifest and a template path, which makes adoption more concrete than a generic planning prompt.
- Good constraint discipline: the non-negotiable rules emphasize unresolved questions, separation of user promises from implementation details, and avoiding invented product truth.
- No install command or support files are provided, so users must infer setup and workflow integration from SKILL.md alone.
- The repository appears to be a single skill file with no references or resources, so edge-case handling and examples may still require user interpretation.
Overview of product-capability skill
product-capability is a planning-to-spec skill for turning fuzzy product intent into an implementation-ready capability plan. It is most useful when you already know the feature goal, but the team still needs clarity on constraints, interfaces, lifecycle rules, data implications, and open decisions before coding starts.
Best fit: PRDs that are still too vague
Use the product-capability skill when a PRD, roadmap item, founder note, or product thread exists but the engineering shape is still implicit. It is especially useful for multi-service work, cross-team dependencies, or features where reviewers keep asking, “What exactly must be true before we build this?”
What it gives you beyond a normal prompt
Unlike a generic “write a spec” prompt, product-capability is oriented around durable capability contracts. It helps separate product promises from implementation constraints, surface unresolved questions instead of guessing, and produce an artifact that can be reused across sessions rather than lost in chat history.
When it is worth installing
If your team often spends review cycles rediscovering hidden assumptions, product-capability install is likely worthwhile. If your work is mostly single-file, low-risk, or already defined by strong existing architecture docs, the skill may add less value than a lightweight prompt.
How to Use product-capability skill
Install and load it in your workspace
Install the skill with:
npx skills add affaan-m/everything-claude-code --skill product-capability
Then open SKILL.md first. For product-capability usage, also inspect any durable product-context file the repo expects, especially PRODUCT.md, docs/product/, or a program-spec directory. If none exists, use the template path referenced by the skill.
Turn a rough ask into a strong input
The skill works best when you give it a product goal plus context, not just a feature name. A weak brief like “add team sharing” leaves too many gaps. A stronger brief is: “Design a capability plan for team sharing across web and API, including permissions, audit events, invite lifecycle, and what happens when a workspace is downgraded.”
Suggested workflow for product-capability for Requirements Planning
Start with the product statement, then ask for the capability boundaries, invariants, assumptions, unresolved questions, and implementation implications. The best product-capability guide outputs usually describe what must be true before work starts, not just a list of features. If the request spans services or teams, ask the skill to call out ownership and contract boundaries explicitly.
Read first, then extend
The repository is intentionally lean, so the most useful first read is SKILL.md. Use it to understand the rule set and artifact target, then adapt the structure to your own repo rather than copying the example verbatim. If your environment already has a canonical product doc location, align the output to that path to avoid creating parallel planning files.
product-capability skill FAQ
Is product-capability only for PRDs?
No. The product-capability skill also fits roadmap items, discussion notes, and founder direction when the real problem is translating intent into a buildable contract. The key requirement is enough product signal to define constraints without inventing them.
How is it different from ordinary prompt writing?
A normal prompt may generate a summary or draft plan. product-capability is narrower: it tries to preserve engineering-relevant truth, make unknowns explicit, and produce a reusable artifact. That makes it better when the cost of a missed constraint is high.
Is it beginner-friendly?
Yes, if you can describe the feature and its context. You do not need architecture expertise to use product-capability, but you do need to provide the best facts you have. If you omit critical inputs, the output will still need review.
When should I not use it?
Do not use product-capability for trivial tasks, isolated UI tweaks, or work already governed by a detailed spec. It is also a poor fit if you want polished marketing copy or implementation code rather than Requirements Planning material.
How to Improve product-capability skill
Give it the facts that matter most
The biggest quality gains come from naming user-visible behavior, system boundaries, and known constraints up front. Include data flow, access rules, rollback expectations, dependency systems, and any policy or compliance concerns that would change implementation.
Make unknowns explicit instead of implied
A strong product-capability input separates confirmed requirements from open questions. If the team has not decided whether an action is synchronous, whether audit logs are required, or which service owns the source of truth, say so directly. That prevents the skill from smoothing over the uncertainty.
Ask for a decision-ready artifact
If your first draft is too broad, ask the skill to tighten scope, list non-negotiables, and highlight tradeoffs that block design decisions. Iterating in this way usually improves the product-capability usage output more than requesting more detail everywhere.
Reuse the same capability frame
For recurring product work, keep the same capability structure across sessions so reviewers can compare plans consistently. The more your inputs reflect the actual operating model of your team, the more the product-capability skill will produce useful guidance instead of generic planning prose.
